v 'An-ObjQCt of'the'invention is to pro vide a simpleerrangement by which a suitable supply offthe coating fluid to the applying member is assured during the entireioperation of -.su ch member over the areQftOIbel coated. In the attainmentof this object, associate with the applying member an inia tiel source of supply,- as a container in which it -1 s immersed, and further contlnue the eup'p yhy other or auxiliary m n sepalqatt from the applyin member, a f a weep? ta'cle, effective after the ithdrewal oflthe applying member from the containerw By:

The coating fluid, as cement, it being assumed that my invention is to be utilized in the preparation of shoe parts to receive their foXing strips,'is' held in a body of suitable depth in such a container as a tank 10, sup ported upon a 'column 12. Pivoted at 14', between opposite walls of the tank and near one extremity, is acarrierarm 16 held normally in a lowered positiontoward the bottom of the tank by allielic'al spring 18 co-operating withthe arm and with the tank wall. The pivot of the arm16 has fixed upon it another arm 20 joined byfa vertical rod 22. with atreadle, which is not illustrated; Cement/is brought from the supply in the tank, when the arm 16 is raised by'the depression'of the treadle, by an applying mem ber, preferably furnished by a brush 24 having an inclined body 25 clamped by screws 26 in a groove inthe extremity of the arm opposite its pivotal support. When not in active use, the brush ish'eld by the spring 18 below the surfaceof the fluid, and is thus prevented from becoming hardened by evaporation. The ends of the bristles or other fibers forming the brush are inclined similarly to thebody portion, giving an applying surface 28. The contourof this i is such as to approach the mean curvature transversely of the foxing area about theentire periphery of a shoe upper, so that,

with the yield of the fibers, the brush will readily conform to the entire surface to'be coated when the. work is passed along the applying surface in a horizontal direction. Spacedfrom one side of the brush, preferably that whichthe workleaves in its advance, is a wall 30 having its outer edge in clined similarly to the applying surface. At the lower edge of the wall is a flange 31 extending across the space and beneath the brush. The wall and flange form, with, the

. brush, a'pocket holding a body of cement over which the workis passed after it has traversed the applying surface' 28. Thus, after the cement has been rubbed into the work .by'the brush, travel across-the pocket will tend to deposit a thicker coating, which,- because of the previous preparation of the surface, will not draw together, but will retain its uniform; distribution. Extending horizontally outwardly from the applying surface of the brush is a work-rest, here shown as consisting of separated rods or rolls 82, 32,- inounted upon a yoke 34, which illustrates in perspective the apis pivoted at 36 upon a sliding block '38.

Ways by means of a screw/'42 tlireade'd'into I the blockand having a collar 44 entering a groove between the ways. Byltnrniiig this s screw, the relation of the rest to the upper edge of the applying surface may be varied,

correspondingly altering the width of the area wliicliis to be coated during the hori'-.

'zontal travel of the work along the. brush.

The pivotal mounting of the rest permits it to be moved'fro'm the working position, 1l.

lustrated' inFigs, 1 and 5 of the drawings, Y

to onefin whichit is wholly clear of the topof the tank, as shownin dotted-dines in Fig. 5, to provide for a substantiallyherto be later described, this cover being bolted to the top 'of the-tank at 48. To give access tothe applying-member during use of the apparatua'the cover has a movable section 50,,hingedat 52 upon one side ofthe tank. Aspring 54associated with the hinge exerts. its tension toforce the vertical edge.

of the section 50 against a corresponding edge of the main cover 46 when the section is 7 brought into co-operation with the tank, thus increasing the efficiency ofthe closure.

As to the organization thus far described, it will be seen that when the arm 16 is raised by the treadle, a quantity of cement is brought by'tlie brush 24 into .a suitable position for application to work moved over the rest 32, This quantity of cement, how e'ver,does not. provide properly for the coating of the entire foxing area,

ceptaole 56, which may be threaded upon the upper extremity of a post or upright 58 rising from the surface of the arm 16 at the rear of the brush. In the bottom of thecup is an opening registering; With a passage 60 E15 I therefore arrange for an auxiliary supply,preferablythrough the instrumentality of a cup or rethrough the post, this passage terminating in a delivery nozzle 62, which is preferably narrowed verticallyand is of such a width as to deliver across the entire upper surface of the brush and to the pocket furnished by the plate 30. -When the arm 16 is lowered,

cup 5 6 is beneath the surface of the body of cement in the tank and becomes filled.

Then the arm is raised totheposition of Figs. 1 and 2, or as shown in dotted-lines in Fig. 4, the cement contained in thecup flows gradually through the nozzle upon the brush, this continuing the supply as it isv distributed over the work.

as appears in Fig. 4 of the drawings, the

would interferefwith its function .i"n deter-- mining clearly the edge :of [the 'toxing area, and I have therefore provided means for removing the cementi from the gage prior r to the application of the workfto the brush.

The gage isshqwn as'inthe; form of IQTO a well-defined' 'line, at the' -upperr edge of the ycoatedareaso 'thatythe. applied accumulation of cement, upon the gage concavedislrihaving a frusto-conical body 64C overhanging and surrounding the nozzle 62, and supported upon a horizontal flange at ,the=lower extremity ot a sleeve 66 'ar,- "ranged.to'turnxabout the post 58. Between the sleeve 66 and thepostjs 'aniintermedi ate sleeve68, alsorotatable'and presently to .be further described, Ania-.70, =clamps collar 72 limits the upward movement of the sleeves; this collar-being fixed tot-he post between'the upper ends '01- the sleeves. and the cupY'56. .About, tl1ezb0tt0in otthe frusto-conical body is a horizontal flange,

74;, whioh' extends over the upper sidefof'the all) . izontal end 80 for engagement Withthe brush and into close proximity with the upperjedge of the applying surface 28. The edge or" this flange, .1 when properly cleaned, resting against the-Work as it is moved over the brush, furnishes a barrier to the upward passage of cement over the Work, and thus maintains the uniformity of this boundary of the toning area. Arranged to co-operate with the upper surtace 'of 'the gage-disk is a contact member'76," preferably formed from some such yield-' able material as felt. fThis member has an inclined edge 78 arranged to hear against the conical surface of the gage; anda horflange 74:. The member orbl'ock 76 may be mounted in a holder 82 having a vertical" stem 88 arranged to slide in a socket formed in the cover 46. .A spring '84,"surrounding the stem, acts to.hold"the-contactflbl0clr normally downward, but yields when the gage-disk strikes""said block upon the elevation of the arm '16, to furnish efi'ective cleaning 'engagement' between the surfaces 78 and 80fand the opposed surfaces oil the disk.
